I think I've preserved peppers just about every way possible & although I realize it's tough to stick to 'approved' safe methods I now mostly do for myself and always do if share with others.
A great starting place:

And the Ball Blue Books printed after 2004 are up to date safety-wise.
Another book I use is "The Complete Book of Small-Batch Preserving" 2nd edition by Topp & Howard
I'm fortunate in that I like 'vinegary' so can pickle pods in the refrigerator and retain some crispness. Dissolve a lot of suger in the vinegar before adding pods and keep in the fridge.
